BODYGUARD Trevor Rees feared he would be murdered if he regained his memory of Princess Diana's death crash, it was claimed yesterday.

BODYGUARD Trevor Rees feared he would be murdered if he regained his memory of Princess Diana's death crash, it was claimed yesterday.

The allegations were made by Karen McKenzie, housekeeper to tycoon Mohamed al Fayed, who insists Diana and his son Dodi were the victims of a murder plot.

Ms McKenzie wept as she told the Diana inquest of a conversation she had with Mr Rees, then known as Trevor Rees-Jones, as he recovered at Fayed's London home weeks after the crash in 1997.

She said the former paratrooper, who had worked for the Fayeds for about two years, remarked: "If I remember, they'll kill me."

The lift he had been waiting for arrived so she did not get a chance to ask him what he meant, she added.

"I can see Trevor in front of me, telling me. It is not something I am ever going to forget," she added.

When it was put to her thatMr Rees denied ever having made such remarks, she replied: "I wish I could do what Trevor has done and just say, 'I do not remember'. But, unfortunately, I do remember."

The inquest in London also heard a senior diplomat deny being part of a plot to cover up the princess being pregnant at the time of her death.

Lord Jay, ambassador to Paris at the time of the princess's death, strongly rejected claims that he demanded her body be enbalmed on the orders of MI5 to hide her condition.

Allegations that the Queen's private secretary, Lord Fellowes, who was also Diana's brother-in-law, was overseeing her murder from the embassy, were also put to him.

Ian Burnett, counsel to the inquest, said: "It has been suggested Lord Fellowes was in Paris on the night of August 30 and commandeered the operations room to organise the murder of his sister-in-law. Was he in Paris?"

Lord Jay replied: "No, he was not."

Harrods boss Fayed is convinced the crash was staged by the secret service on the orders of Prince Philip to prevent the couple's planned marriage.

Lord Jay said a team from SIS - better known as MI6 - were operating at the embassy at the time, as was a representative of the security service MI5, but he had no reason to believe they had anything to do with the crash.

He said the team were there to work with the French on counter-terrorism, drugs operations and intelligence.

Meanwhile, Fayed's legal adviser Stuart Benson told the inquest that Dodi had hinted to him in a phone call two days before his death that he and Diana had become engaged.

He said: "Pretty much the exact words were, 'Can't really talk over the phone but my friend and I have very exciting news'."

The lawyer, who has worked for Fayed for more than 15 years, told the inquest Diana was not mentioned by name by Dodi as he was concerned that his calls might be bugged.
